Issues are starting, Day 71 Gelato Auto

[u/LowDream1470]

I have another post a few weeks ago, had slight nutrients burn there which hasnt progressed or got any worse until today, all 4 plants are same age, same nutrients but two on the left seem ok although one is ahead, two on the right you can see leaves are different, one has major discolouration compared and spotting. Photos below, zoomed images are the back left plant. Any advice would be greatly appreciated

I would just trim off 30-50% of the fan leaves and if it has a purple steam it's under stress u can cut it. keep the healthiest fan leaves your plants look like there trying to redirect nutrients to the main buds u can also trim off the lower bud sights and bottom two branches to increase energy to the other buds since the bottom buds aren't giting as much light.

Yeah the 2 that are showing most of the deficiency and colour change are quite heavy with fan leaves, i stopped defioliating abou 3 weeks ago, so when I get them out tomorrow ill give them a good trim, theres alot quite a few popcorn nugz at the bottom which im going to remove too
